Features: 

A New High-Quality 4 Line 20 Character Lcd Module

Not Only Set The Contrast Control Knob Selector Switch

Also Has A Backlight And Iic Communication Interface.

For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the for Arduino Sensor Shield V5.0 sensor expansion board IIC device interface can, G M 4P sensor connection cable, programmed through the for Arduino controller, you can easily identify the slogan, sensor data records

 

Specification:

Interface: I2C

I2C Address: 0x27

Pin Definition : GND VCC SDA SCL

Back lit (Blue with White char color)

Supply voltage: 5V

For Arduino Test Code:

 

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

 

LiquidCrystal_I2C lcd(0x27,16,2); //set the LCD address to 0x27 for a 16 chars and 2 line display

 

void setup()

{

lcd.init();

lcd.backlight();

lcd.setCursor(0, 0);

lcd.print("b2cqshop");

lcd.setCursor(0, 1);

lcd.print("Voltage: ");

lcd.setCursor(13, 1);

lcd.print("V");

}

void loop()

{

int val;

float temp;

val=analogRead(0);

temp=val/4.092;

val=(int)temp;//

lcd.setCursor(9, 1);

lcd.print(0x30+val/100,BYTE);

lcd.print(0x30+(val%100)/10,BYTE);

lcd.print('.');

lcd.print(0x30+val%10,BYTE);

delay(100);

}
